IRRIGATING 0R SPRINKLING SYSTEM.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed April 23, 1920. Serial No. 375,962.

T 0 all whom it may concern:

Be it known that I, GEORGE E. MARCH, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented new and useful Improvements in Irrigating or sprinkling Systems, of which the following is a specification.

The present invention relates to irrigating or sprinkling systems; and its object is, generally, to provide a system of that character improved in various respects herein after set forth; and more particularly. to provide in such a system an improved mounting for a turnable horizontally disposed pipe having a lateral irrigating vent or vents; and further, to provide an improved water motor for thu's turning such a pipe; and further, to provide such a motor depending non-turnably from such a turn able pipe; and further, to provide improved means for operating such a motor; and further, to provide improved means for supplying water to the motor; and further, to provide improved means for controlling the How of water thus supplied.

These and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure or structures hereinafter particularly described and illustrated by the accompanyinq drawings, in which igure 1 is a view in side elevation of a' part of a sprinkling system comprising a horizontally disposed pipe and a water motor for turning the same about its longitudinal axis;

Fig. 2 is a transverse sectional view of said pipe taken on a plane corresponding to line 22 of Fig. 1, and showing also a mounting for said pipe;

Fig. 3 is a front View of a water motor depending from an irrigating pipe;

Fig. 4 is a side view of the same;

Fig. 5 is a like view of the same, enlarged,

certain parts being shown in section in order to display the passages therethrough;

*3g. 6 is like view of a portion of the same, similarly sectioned, and showing the parts in another position;

the pipe about its longitudinal axis in order that the streams or sprays issuing from said vents may sweep from one side of the pipe to the other. The pipe 1 may be thus turnably mounted in any suitable manner, as in hearings in which the pipe may be rocked; preferably however, this pipe is supported on and is adapted to roll along the horizontally disposed upper surface or track 6 of the supports 7 (as shown in Fig. 2), means being provided for limiting the rolllng travel of the pipe, as the upwardly extending stops 8 at the ends of said track or surface ('3. By employing the mounting shown in Fig. 2 the following desirable ends are attained: The pipe is more readily positioned on and removed from the supports than it could be if it turned in closed rock bearings; the friction necessarily incidentto all rock bearings is eliminated; and any binding of the pipe occasioned by the axial non-alinement of spaced rock bearings, re sulting from a faulty installation or a subsequent settling movement of the supports, or occasioned by any warping of the pipe from an axially direct line, is also eliminated.

The'pipe 1 is turned or, as shown in Fig. 2, is rolled back and forth by suitable means, as the water motor designated generally 5. In the construction illustrated, this motor is supported by the pipe, depending therefrom but not turnable therewith, as by the rollers 9 journaled on the motors upwardly extending arms 10. A weight indicated at 11 may be attached to the lower end of the motor to reinforce the effect of the motors own weight in holding it from turning with the pipes turning or rollin movement. This motor comprises the cylinder 12 and its piston 13 the cross head 14 of whose rod 29 is slidably guided by the arms 10 and is connected by a link 15 to a radially extending arm J6 of the pipe for turning or rolling the same. Water for operating the motor is supplied to the cylinder from a suitable source and by-suitable means, preferably the following: The pipe has a vent 17 (hereinafter called the second vent in contradistinction from any of the pipes irrigating vents or nozzles 4) from which second vent water passes from the pipe through a flexible tube 18 into a member, designated generally 19, having a main passage 20 whereby the water flows into the cylinder and having also the auxiliary passages 21, 22. A rocking valve 23 is operable by the piston for con trolling the flow of water through these passages, by theengagement-of the arm 24 of the piston rods cross head 14 with the collars 25, 26 adjustable on the rod 27 pivotally connected to said valves lever arm 28. The operation of the parts is illustrated in Figs. 5 and 6. In Fig. 5 the parts are shown in the position in which water is being-admitted into the upper end of the cylinder to force the piston downwardly. In this position, the valve 23 has been turned to admit a portion of the water supplied from the tube 18 into the lower auxiliary passage 22 which portion entering the lower end of the chamber 30 in the member 19 has raised the sliding valve 31, thus bringing its annular passage 32 into registration with the main passage 20 and with the passage 33 in the rod 34 (which with the other rods 35, 36, 37 connect the heads 38, 39 of the cylinder), from which passage 33 the greater portion of the water supplied from the tube 18 enters the upper end of the cylinder and forces the piston downwardly, which movement expels the water below the piston through the passage 40 in said rod 34 and the annular passage 41 in the sliding valve 31 and out through the waste vent 42. The water in the chamber 30 above the sliding valve 31 has been expelled, by the upward movement of said valve, through the upper auxiliary passage 21, the auxiliary opening 53 in the valve 23 and out through the waste vent 43. The further descent of the piston causes the arm 24 of the cross head 14 to strike the lower collar 26 and turns the valve 23 to the position seen in Fig. 6, wherein the parts are shown in the position whereby the piston is forced upwardly, a portion of the water from the tube 18 now flowing through the upper auxiliary passage 21 thus forcing the sliding valve 31 downwardly and expelling the water below it through the lower auxiliary passage 22, the auxiliary opening 52 in the valve 23 and out through the waste vent 45, and the greater portion of the water supplied from the tube 18 flowing into the lower end of the cylinder through the annular passage 32 of the sliding valve 31, and the passage 40 in the rod 34, thus forcing the piston upwardly, which movementexpels the water above the piston through the passage 33 in said rod 34 and the annular passage 46 in the sliding valve 31 and out through the waste vent 47. The further upward movement of the piston causes the arm 24 of the cross head 14 to strike the upper collar 25 and turns the valve 23 again to the position seen in Fig. 5.

A valve 50 may be employed for controlling the flow of water through the main passage 20 independently of the How through the auxiliary passages 21, 22, so that the amount of water supplied from the tube 18 to the said main passage may be governed relatively to the amount of water to the auxiliary passages. A valve 51 is shown for controlling the water flow through the tube 18.

The stroke of the piston (i. 6., the dis tance it travels back and forth) determines the angular extent of the irrigating pipes turning movement; and the limits within which the same stroke of the piston is confined determines the angular position of the same angular extent of the pipes turning movement. Both the angular extent and the angular position of the angular extent of the pipes turning movement may be controlled by adjusting the collars 25, 26 (by their set screws 54), these collars being moved farther apart or closer together on the rod 27 to control said angular extent, and both being moved up or down on the rod to controlsaid angular position of such an ular extent.

. t will be seen that the water for irrigating does not pass through the motor, but passes through the irrigating vents 4 directly from the source of supply. The water for irrigating and that for operating the motor may therefore be interrelatively proportioned, as by the valve 51, so that the motor may turn the irrigating pipe 1 as fast as may be desired independently of the amount of water issuing from theirrigating vents.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.
